Diana tarsier
Dian's tarsier (Tarsius dentatus ), also known as the Diana tarsier, is a nocturnal primate endemic to central Sulawesi, Indonesia. Its head-body length is 11.5–12 centimetres (4.5–4.7 in) and it has a tail of 22 centimetres (8.7 in). Dian's tarsier lives in rainforests. It was formerly called T. dianae, but that has been shown to be a junior synonym.
It is highly adapted to vertical clinging and leaping, like other tarsiers, and has a strict live animal diet, consisting mostly of insects. Due to human intervention in the forest of South-east Asia, Dian's tarsier tends to adapt its ranging behavior based on the degree of human intervention. Slightly disturbed habitats have been shown to have little effect on the Dian's tarsier, but with larger disturbances, the habitat is less suitable.
First claimed as a new species by Miller and Hollister in 1921.

starts withThe weight of adult Dian's tarsier ranges from 100 to 150 grams. This species is characterized by a greyish buff color to their wooly fur, a black spot is present on each side of the nose and white-colored fur appears on the middle lower lip and on both sides of the upper lip.
Dian's tarsier is found in the primary rainforest of the lower mountains of central Sulawesi. It can also be found in habitat modified (disturbed) by humans such as secondary forests with logging, agroforestry or intensive agriculture.
Home ranges of mated males and females pairs overlap. There is slight overlap between the home ranges of different groups. The male home range is slightly larger than the female's in undisturbed habitat with average home ranges sizes of 1.77 hectares and 1.58 hectares respectively.
Dian's tarsier eats most commonly crickets, grasshoppers and moths.
Females of this species typically give birth to one child per year. Reproduction does not appear to vary by season. Dian's tarsiers use infant parking.
